Hi everyone I am new to this site and sport as my name suggests. I just bought a extreme buggy and on my first start the engine started reving really high when trying to adjust it it will cut out what problems do i seem to be facing and does it require a new engine or can it be fixed any suggestions.

Trying to analyze and solve engine problems in this manner is like trying to give a haircut over the phone [X(]

Give as many details as you can about what you do, and what the engine does and we can take it from there...

First thing First-Welcome to RC Universe! You'll find people here are usually very helpful when someone has a problem to work out.

Like Bob said, the more information you give the people here the easier it is to help. From your statement I'm guessing you have a buggy with a Nitro motor in it. The manual should tell you where to set the needle valve, just close it (but don't over tighten it) and open it the recommended amount of turns. If it shot up in RPMs when you started it you may have to reverse the servo direction, it sound like it's wide open when the throttle on the radio is at idle. At any rate tell us what brand of engine you have and the size, (like .26 etc.). If this is a glow (nitro) motor you may want to post you question in the Glow Engines forum for better help with your problem, this one is for Gasoline (petrol) engines.

Good luck.
